This hand-drawn classroom-style poster clearly compares 2D (flat) and 3D (solid) shapes using simple notes and friendly doodles. On the left side, it shows 2D shapes like squares, rectangles, triangles, and circles, along with their area and perimeter formulas. On the right side, it presents 3D shapes such as cubes, rectangular prisms, cylinders, and spheres, including their volume and surface area formulas.
The design looks like a teacher wrote it by hand on clean white paper, with neat labels, light colors, and fun cartoon-style drawings to make learning more engaging. At the bottom, a quick summary explains the key difference: 2D shapes are flat, while 3D shapes have depth. This makes it a perfect visual aid for students learning basic geometry.
